UNITED STATES PATENT OFFIC AUGUST KRAUTTER, OF BRUSSELS, BELGIUM, ASSIGNOR OF ONE-HALF TO HENRY BAUMANN, OF BROOKLYN, NEW YORK.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 447,956, dated March 10, 1891.

Application filedOctober 17, 1890. Serial No. 368,473. (No model.) Patented in Belgium March 14, 1889, No. 85,385, and April To all whom it may concern.-

Be it known that I, AUGUST KRAUTTER, of the city of Brussels, Belgium, a citizen of Belgium, have invented certain new and useful Improvements in Lubricators, (for which I have obtained Letters Patent in Belgium March 14, 1889, No. 85,385, and April 13, 1889, No. 85,818,) of which the following is a specification.

The object of my invention is to provide a new and improved lubricating device which can be applied on all kinds of bearings, and is so constructed that no oil is wasted and all the superfluous oil that is conducted to the r 5 journal runs back into the oil-receptacle to be used over again.

The invention consists in a lubricatingwick composed of spirally-twisted wire having a covering of cotton.

The invention also consists in the construction and combination of parts'and details, as will be fully described hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a bearing provided with my improved lubricator. Fig. 2 is a vertical transverse sectional view of the bearing provided with a modified construction of the same. Fig. 3 is 0 a vertical longitudinal sectional view of another construction of my improved lubricator applied on a crank-pin. Fig. 4c is a vertical sectional view of a crank-connection provided with my improved lubricator. Fig. 5

3 5 is a vertical transverse sectional view of my improved lubricator as applied on a loose pulley. Fig. 6 is a vertical longitudinal sec tional view of a velocipede-pedal provided with my improved lubricator. Fig. 7 is a transverse sectional view on the line 7 7, Fig. 6; and Fig. 8 is a vertical transverse sectional View on the line 8 8, Fig. 7.

Similar letters of reference indicate corresponding parts.

5 As shown in Figs. 1 and 2, the bearingshells are made of two half-sections A and B, the bottom section being provided on its top edges with a longitudinal groove 0 for collecting the superfluous oil from the journal D. Each section A and B is provided at the end with an interior semi-annular groove E,

as shown in Fig. 1.

and from the grooves E in the bottom sections the channels F, formed in the bottom section B, run to a tube G, made integral with the lower section B, from which tube the oilreceptacle'H .is suspended, that has a top filling-opening closed by a screw H and abottom cleaning-opening H A wick K is passed through the tube L, extending from near the bottom of the oil-receptacle H, through the tube Gr and through a suitable channel in the bottom bearing-section B to about the center ofthe bottom part of the journal, the upper end of the wick K being in contact with the journal, While its lower end rests on the bot- 6 5 tom of the oil-receptacle H. Said tube is composed of spirally-twisted strands of thin steel wire I I, which are provided with a covering of cotton, so that the oil is drawn up from the oil-receptacle to the journal by capillary attraction. The lower parts of the wire are left uncovered, as shown in Fig. 1, so that the impurities which collect at the lower part of the oil-receptacle are not drawn up by the covering. The lower ends of the wires rest on the 7 bottom of the oil-receptacle and form an elas tic or cushioned supporti'or the Wick. As the shaft rotates the oil is drawn from the wick to the journal of the shaft, While the superfluous oil is conducted to the grooves O Oand E and through the channels F F and F back into the oil-receptacle, so as to prevent the oil oozing out at the-end of thejournal. The journal is provided with two collars M M within the grooves E, as shown in Fig. 1.

In some cases there is not sufficient space to apply the oil-receptacle H, and in place of.- the same I use a tube N, Fig. 2, projecting through the bottom bearing-block and serving as an oil-receptacle, the wick, which is very short in this case, projecting into the inner end of said tube.

For lubricating crank-pins the oil-receptacle H is suspended from the end of the connecting-rod O, and the wick-tube projects from the crank-pin downwardinto said receptacle, as shown in Fig. 4. For the lubrication of a crank-pin of a locomotive the construction shown in Fig. 3 is used, the channels EE and F F being provided in the manner described, IOO

The oil-receptacle H is suspended from the bottom section of the journal-box and is provided with a fillingchannel 0, closed by a screw-plug 0 A cylinder P, having its bottom closed by a screw-plug P, is connected by a short branch tube Qwith the bottom part of the oil-receptacle, the bottom of said cylinder P being some distance below the bottom of the oil receptacle. A plunger or piston Q in saidcylinder I is pressed upward by a spring Q and a handle Q projects from the top of the plunger.

lVhen it is desired to ascertain whether the oil-receptacle is filled or not, it is only necessary to press down the plunger Q to below the connecting-tube Q. If there is oil in the receptacle II, the top of the plunger Q will be covered with oil when it is raised again by the spring Q The impurities from the oilreceptacle II pass through the connectingtube Q into the cylinder P and can be removed by unscrewing the plug 1?. For loose pulleys I use an oil-receptacle, as shown in Fig. 5, which receptacle is provided with a filling-tube R. A wick-tube L projects up into the oil-receptacle H, and as the pulley revolves the oil comes in contact with the wick and passes along the same to the shaft.

For bicycle-pedals the oil-chamber is made cylindrical, as shown in Figs. 6, 7, and 8, and is provided at its ends with grooves s for collecting the oil, the pedal-spindle T being provided with the collars T within said grooves S. Tubes U extend from said grooves S into the oil-chamber H, and the wick-tubes Vproject radially from the inner walls of the oilchamber, the inner ends of the wicks being in contact with the spindle T. The oil-chamber H forms the main support of the pedal and rotates on a pedal-pin T. The superfluous oilpasses from the chambers S through the fine tubes U back into the oil-chamber.

By means of my improved lubricating device all waste of oil is prevented, as the superfluous oil does not drop from the end of the bearings but passes back into the oil-receptacle. The different parts of the machinery which are lubricated are thus kept clean, and the quantity of oil required for lubricating purposes is reduced, while the journals are at all times entirely lubricated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a lubricating 'device, a lubricating wick composed ofthin spirally-twisted wires and a covering'of cotton, substantially as set forth. I

2. A lubricating-wick composed of thin spirally-twistedwires and a covering of cotton for the same, the lower ends of the wires being uncovered and curved, so as to form an elastic cushion for the wick, substantially as set forth.

3. The combination, with a journal-box, of an oil-receptacle, a cylinder connected by a branch tube with the bottom of said receptacle, the bottom of said cylinder being below the bottom of the oil-receptacle, and a plunger in said cylinder, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
